<div dir="ltr"><div>Hi again,</div><div><br></div><div>Further to the below, what I would actually prefer to do is use the depsamplesT test on my data structure containing averages over trials for each subject (i.e. the output of ft_timelockanalysis).</div><div><br></div><div>But every time I try, I get the message "length of the design matrix (2) doesn't equal the number of observations (694)" - no matter what the dimensions of the design matrix are. I've set up the matrix exactly as specified in the tutorial (relevant to my data of course). Any idea what this error is about? <br></div><div><br></div><div>Thanks again,<br></div><div>Kate<br></div><div><br><div class="gmail_quote"><div dir="ltr">On Tue, Oct 23, 2018 at 2:04 PM Kate Stone <<a href="mailto:katemsto@gmail.com">katemsto@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div>Hi all,</div><div><br></div><div>I've been following the tutorial here to do a time-locked perm test on ERP data: <a href="http://www.fieldtriptoolbox.org/tutorial/cluster_permutation_timelock" target="_blank">www.fieldtriptoolbox.org/tutorial/cluster_permutation_timelock</a></div><div><br></div><div>I have computed grand averages for my two conditions and am using indepsamplesT with ft_timelockstatistics(cfg, GA_1, GA_2).</div><div><br></div><div>But what should the design matrix be? The example in the tutorial doesn't apply as I am using grand averages and the reference for ft_timelockstatistics doesn't mention the design matrix, although it is definitely required.
